This invention relates to mine cars and has as an object to provide an improved mine car ot composite construction. 1t is also an object of this invention to provide a mine car of the type speciiied in which the side tloor portions are tormed integral with the sills and are corrugated to receive bracing members. lt is also an object of this invention to provide an improved bumper for mine cars of the type speciiied which will facilitate repairs to the car tloor. It is also an object of this invention to pro vide a mine car ot' improved construction which is rugged and inexpensive to manufacture and readily and cheaply repaired and which is adapted to be readily modiiied in various details without modification ot' the main features of the construction.

With these and other objects in view a mine car constructed in accordance with this invention comprises, asshown in the drawings, metal plates 1 forming the side floor portions of the car and having their inner edges bent to vform Z-shape sills having vertical webs 2 and inwardly projecting bottom flanges 3, the-top flanges of the sills coinciding with and being part of the side Serial No. 35,639.

receive the wheels and extending tothe outer edges o'l5V the plates l, the openings in the plates being covered in the structures shown in Figs. 1 to G by wheel hoods l() formed integral with the plates l by pressing portions of the plates upwardly. ln the modilied construction shown in Figs. 7 to 9, the openings ll in the plates 1 are .termed by cutting away portions of the plate 1, the openings being covered by wheel hoods ll secured to the side plates 1 by rivets 162 and bolts 10. lhe side plates l are also provided with equally spaced corrugations 18 which extend inwardly troni the ilanges Ll and are merged into the plates 1 adjacent the sills. The flanges et are continued around the corrugations in each ot the structures and in the structures shown in Figs. l to t5 the iianges l extend about the outer edges ot' the wheel hoods' 1G which extend to and merge into the ange et.

In the structures shown in Figs. 1 to 3 and 7 to 9, inclusive, wood sides 20 are shown carried by the side floor portions and .engaging the iianges 4 while in the modification shown in Figs. a to (5 metal sides 201 are shown secured to the flanges 4. In each of the constructions the sides are braced by strap brace-s 22 extending beneath the car body ll'rointhe top ot' one side to the top. ot the other side. The braces 22 are secured to the wood sides by bolts 23 and to the nietal sides by rivets 231. The braces 22 lie in the corrugations 18 and are fastened therein by rivets 24 and are secured to the langesl of the plates l by bolts 23 or rivets 231 and to the flanges 3 ot the sills by the bolts 9. f.

Extending from end to end of the car is the inverted U-sliape drawbar or buffer meinbeil 2G having laterally projecting iianges 28 secured to the braces 22 by the bolts 34. Between the drawbar 26 and the sills are placed the planks 32 fastened to the strap braces 22 by bolts 8l and which, With the vveb 8b' of the dravvbar 2G7 form the center lloor portion of the car. rlhe dravvbar 26 and some planks 82 project beyond tie end braces 22 and have secured thereon bumpers 4 0. rljhe bumpers l0 comprise top plates 42 and bottoni plates lll which extend inwardly lar as the inner edges olf the end braces 22 and are secured thereto by the bolts il@ which entend through the upper and lower plates Ll2 and t, planks 82 and iiller members ii8 which are placed between the bottoni plates la and the bottoms oil' the planks The top and bot-tom plates l2 and del are joined by 'face plates 50 which curve slightly from end to end and have horizontal depressions lying on each side ot the centers forming anti-climbers, the bottoms ol the depressed portions forming surfaces which engage the outer ends olz the planks 32. rl`o the web 8G at each end ol the dravvbar 2li is riveted a dravvbar member 52 which has its outer end spaced from the bumper Ll() to provide an opening to receive the usual coupling' link and is provided with an opening` to receive the ycoupling pin 53 Which engages also iu alined openings in the bumper` ll() and the drawbar 23.

Extending across from sill to sill in line with cach brace 22 are ties 50 which roel upon the center tloor portion and side iioor portions and are secured to the side floor portions by rivets 62 and to the center floor portion by the bolts 3l which secure the planks 32 to the braces 22. fit one end the car body is closed by a svvingingend gate 66 carried by arms 68 pivotally connected to the car side at TO and provided With an opening :tor the draWbar member At its other end. the car body is closed by a lined end 72 secured in place by transverse brace 74 and vert-ical braces 76.

Secured to the flanges 8 oiz the` sills are brackets 8O in which is pivotally mounted a shaft 8l having crank arms 82 pivot/ally connected to ends ot flexible brake bands 83 which lit over the treads of the Wheels and have their opposite ends riveted to bracket-s 8st secured to the adjacent brace 22. At one end the shalt 8l is provided with a crank arm 85 pivotally connected by a link 86 to a brake lever 87 pivotally mounted in a bracket 88 secured to a side plate l. The brake lever 87 extends upwardly inside the body of the car through an opening in the side iloor l and has .its upper end bent outwardly and projecting over the side ol the car Which is slightly lower at this pointin order to keep the `brake leverfrom extending above the upper edge of the car side. The brake lever is provided with a projection adapted to engage in the teeth 89 formed on the angle 90 secured to the car side 2O to maintain the. brake lever in brake applied position. To protect the brake lever from the lading there Leliases is provided a plate 9]. having lianges by which it is secured to a car side, an end and the .floor and which lorms, with the car side. end and floor, a pocket in which thel brake lever operates.

lt will be noted that placing the braces 22 in the corrugations 18 provides a clearance beneath the side lloor portions at the ends of the car 'which entends to the bottoms of the side sheets l and renders this type ot car especially suitable for use 'With end dumping devices. lt "will also be noted that in the structures shown in Figs. l to 6 extending the Wheel hood lll to the car side, as shown. pro-` may be moved longitudinally to remove them 'l'roni the car upon removal of the bolts which secure them in position. Upon removing the outside planks, the inner planks, when un bolted, may be moved over against the sills and then vwiil'hdraWn past the bumpers Without removing the bumpers from the drawbar member 26. rlhe planks 82 which engage with the bumpers are of the same length so as to engage with lhe bottoms ol the horizontal depressions formed in the bumpers. Planks may be inserted by reversing the operation described above.
